Upgrade your PETKIT water fountain with the Filter Unit 3.0, designed for superior filtration performance and long-lasting cleanliness. Unlike generic filters that compromise on materials, these units use original, high-quality components to deliver crystal-clear water for your pets. The multi-layer filtration system combines double filter layers with a high-density micropore filter to effectively trap pet hair, debris, and impurities, ensuring your cat or dog always has access to fresh, safe drinking water.
Compatible with the PETKIT Eversweet 2S, Eversweet 3, Eversweet 3 Pro, Eversweet Solo, Solo 2, Solo SE, and Pure Drink models, this 5-pack provides convenience and efficiency for multi-pet households or frequent replacements. For optimal performance, soak the new filter in clean water for at least 10 minutes before installation. Replace every 30 days (or when the LED indicator signals a change), and remember to clean the fountain and refresh the water weekly to maintain peak functionality. Trust PETKIT’s upgraded filtration for a healthier, happier pet.
